一般描述
Aluminum potassium sulfate dodecahydrate is an inorganic sulfate salt of aluminum and potassium. Linear growth rates of (100), (111) and (110) faces of its crystals have been investigated.
应用
- Extraction and characterization of lignin from oil palm biomass via ionic liquid dissolution and non-toxic aluminium potassium sulfate dodecahydrate precipitation processes.: This study explores an environmentally benign method for extracting lignin from oil palm biomass using ionic liquids, followed by the precipitation of lignin using non-toxic aluminium potassium sulfate dodecahydrate. The process is notable for its eco-friendliness and efficiency in lignin recovery, highlighting a potential application in bio-refining technologies (Mohtar et al., 2015).
- Reduction of house-dust mite allergen concentrations in carpets by aluminium potassium sulfate dodecahydrate (alum).: This research investigates the effectiveness of aluminium potassium sulfate dodecahydrate (alum) in reducing allergen concentrations in household carpets. The study demonstrates alum′s potential as a simple and cost-effective method to significantly decrease allergen levels, thus contributing to improved indoor air quality and reducing allergen-related health issues (Sevki et al., 2006).
